U.S. Sen. Lindsey Graham has more than $7.6 million spend, after raising more than $1.3 million from October through December, making it his second-best career fundraising quarter, his campaign announced Friday.

He raised more than $5 million in 2013 for his re-election bid, and more than $10.7 million in the six-year election cycle, according to his campaign.

Details on Graham's fourth-quarter contributors are not yet available.

But Graham's third-quarter boost came with the help of donations from: former U.S. President George W. Bush; Henry Paulson, former U.S. treasury secretary and chairman and CEO of Goldman Sachs; George Shultz, U.S. secretary of state for President Ronald Reagan; and Nobel Prize winner Henry Kissinger, U.S. secretary of state under Presidents Richard Nixon and Gerald Ford.

“Senator Graham has been blown away by the incredibly strong support from every corner of South Carolina,” said campaign manager Scott Farmer. “The momentum continues to build, and we’re looking forward to a spirited campaign on Senator Graham’s conservative record.”
